You need to load the ltt-control module to be able to control tracing from user
space. This is done by issuing the command :
cd /tmp
/usr/local/bin/genevent /usr/local/share/LinuxTraceToolkitViewer/yourfacility.xml
cp ltt-facility-yourfacility.h ltt-facility-id-yourfacility.h \
- /usr/src/linux-2.6.12-rc4-mm2-lttng-0.4/include/linux/ltt
+ /usr/src/linux-2.6.12-rc4-mm2-lttng-0.4.1/include/linux/ltt
cp ltt-facility-loader-yourfacility.c ltt-facility-loader-yourfacility.h \

+ /usr/src/linux-2.6.12-rc4-mm2-lttng-0.4.1/ltt
* edit the kernel file you want to instrument
- Add #include <linux/ltt/ltt-facility-yourfacility.h> at the beginning
of the file.
- Add a call to the tracing functions. See their names and parameters in
